1. Introduction
The Long Range Ethernet Extender, a G.SHDSL (Single-pair High-bit-rate Digital
Subscriber Line) Ethernet Network Extender, provides a broadband full duplex
transmission with bandwidth aggregation up to 10.8Mbps over two pairs of copper
wire for point-to-point LAN connectivity between two Ethernet networks. This is
enough speed to support VoIP, Web hosting, and teleconferencing.
The EIDM-EXTEND-2 conforms to the ITU-T Rec. G.991.2, to meet G.shdsl.bis
network requirements. It offers a cost-effective symmetrical broadband solution for
applications such as LAN to LAN, Internet access, and VoIP. Each Ethernet
Extender can be configured into either STU-C (SHDSL Transceiver Unit) for central
side or STU-R for remote side.
Distances can reach up to 7,000 feet (about 2.1 Km) and 10,000 feet (about 3 Km) at
the maximum rate of 10.8 Mbps and 9.216Mbps with two pairs of 24AWG (0.5 mm)
copper wire, and could reach 20,500 feet (about 6.2 Km) at 192Kbps. Users can also
select a fixed data rate for the copper lines ranging from 192Kbps to 10.8Mbps. The
Ethernet Extender provides a console port for users to configure the settings and to
monitor the connection status.

5. Installation Procedures
Step 1: Connect the SHDSL line (1 or 2 pairs) to the RJ-48 connector (marked Line) on
the rear panel of the Ethernet Extender.
Please note: RJ-48 and RJ-45 connectors are physically identical
RJ-48 Connector Pin Assignment for SHDSL Line Interface, straight through
Note: RJ48 connectors hold up to eight wires. They use the same plug and socket as an RJ-45 but have
different pin-outs. RJ-48C is commonly used for T1 lines and uses pins 1, 2, 4 and 5.
Step 2: Connect the Ethernet interface to the RJ-45 Port(s) (marked LAN1 and LAN2)
with the included CAT5 cable.
Step 3: Connect both Ethernet Extenders to the AC outlet using the power cords
included and turn on the power switch.
Step 4: Please refer to the Console Port Control section for initial serial interface setup.
Set one Ethernet Extender as STU-C (Central) from console port, and the other
Extender as STU-R (Remote). Type 1 in the Main Menu to select Configuration
menu, then type 1 in the Configuration menu to select DSL Mode. Make sure one
unit is STU-C and the other is STU-R. Extenders will automatically connect with
each other. There will be 2 or more handshaking cycles when Adaptive is selected
as the speed setting. The system will adapt to the maximum rate possible
according to the loop distance. The maximum Adaptive rates are 4,608Kbps for
single pair and 9,216Kbps for two pair mode. The maximum fixed rate is
10.8Mbps.

7. Console Port Control
The Long Range Ethernet Extender provides an RS232C console port for users to monitor
the status and configure the Extender through a VT100 terminal. This section covers the
operation procedures, settings and for all screen selections.
Connect the RS232 cable to the COM port of the computer as shown in the following
diagram. Set the personal computer to VT100 or VT102 type through HyperTerminal. Press
the <ESCAPE> key and the main menu will be shown on the screen of the terminal. The
terminal operations can then start.
If the <ESCAPE> key is pressed and the screen of the terminal does not display, this may be
due to the incorrect COM port setting. Choose the right COM port (COM1 or COM2) on the
computer, and press the <ESCAPE> key again to make sure that the main menu appears on the
terminal screen. Note that the COM port should be set as 9600bps, none parity, 8 data bit, and
1 stop bit.
